When the absolute position of thedescribed object changes, the relative position relationship may alsochange accordingly.

The first aspect of the embodiments of the present disclosure proposesan electronic board, which can replace paper boards and can displaycontent according to control instructions.

As shown in FIG. 1 , the electronic board includes a first communicationcircuit 11, a first control circuit 12, a first display screen 13 and asecond display screen 14. The first display screen 13 and the seconddisplay screen 14 is arranged back-to-back (that is, the display screensface opposite directions or approximately the opposite directions), sothat the display screens of the electronic board face two directions;for example, the first display screen and the second display screen aredisplay screens independent of each other, or the first display screenand the second display screen form a double-sided display screen.

Taking the first display screen and the second display screen beingindependent display screens as an example, the screen sizes of the firstdisplay screen 13 and the second display screen 14 can be set accordingto requirements, and there is no limitation here. It should beunderstood that the second display screen 14 is not necessary, and insome embodiments, the electronic board may only include the firstdisplay screen 13.

The first communication circuit 11 is configured to receive ato-be-displayed board content sent by an opposite terminal apparatus (amobile phone or an upper machine). For example, in the case that theboard is a table plate, the board content includes relevant informationof the participants of a meeting, such as one or more of names, workunits, and titles. In the case where the board is a working stationplate, the board content includes the information of the personnel atthe working station, working station reservation information,advertisement information, and the like. In the case where the board isa room number plate of the conference room, the board content includesthe scheduling information and advertisement information of theconference room.

For example, the board content is sent to the electronic board by a peerdevice (electronic device). For example, the board content is directlyused for display after being sent to the electronic board by theelectronic device. For example, the board content is a picture generatedby the electronic device according to the user's editing of templates(such as electronic table plate templates, working station platetemplates, room number plate templates), or a picture uploaded by a useron the electronic device, the picture is created by the user throughother tools and uploaded to the electronic device.

The first control circuit 12 is configured to make the first displayscreen 13 and/or the second display screen 14 display the board content.For example, as shown in FIG. 2 , the electronic board may furtherinclude a display driving circuit 15 for driving the first displayscreen 13 and the second display screen 14 to display the board contentaccording to the control signal of the first control circuit 12 and theboard content provided by the first control circuit 12. In response tothe first communication circuit 11 receiving the board content, thefirst control circuit 12 causes the display screen to display the boardcontent. And in response to the first communication circuit 11 receivingthe updated board content, the first control circuit 12 causes thedisplay screen to display the updated board content.

For example, the first display screen 13 and/or the second displayscreen 14 are liquid crystal display screens, OLED display screens,quantum dot display screens, etc., and may also be electronic inkscreens.

It can be seen from the above embodiments that the electronic boardprovided by the embodiments of the present disclosure receives the boardcontent from the peer device (mobile terminal such as mobile phone, oran upper machine such as conference management device, conferencemachine, etc.) through the first communication circuit and display theboard content by the first display screen and/or the second displayscreen. On the one hand, it facilitates the display of boardinformation, no need to make paper boards, it is more convenient to use,and also saves resources. On the other hand, through the board contentis displayed on both sides, in addition to other participants, theparticipant corresponding to the board content can also see the displaycontent, which is helpful for the participants to find seats and correcterrors.

For example, the first communication circuit 11 may include at least oneof a wired communication circuit (such as USB) and a wirelesscommunication circuit (such as WiFi, Bluetooth, and Near FieldCommunication (NFC)). In some embodiments, the communication between thefirst communication circuit 11 and the electronic device may be achievedthrough wireless communication. For example, the first communicationcircuit 11 is configured to receive the board content from an electronicdevice through a wireless communication circuit; wherein the boardcontent is a data stream encapsulated by a private protocol. Forexample, the private protocol may include a Bluetooth private protocolor a 2.4 GHz private protocol. In this way, the board content isreceived through the wireless communication mode without a wiredconnection with the electronic device, which makes the use of theelectronic board more convenient. At the same time, the low-powerprivate protocol ensures the safety of transmission. In addition, theprivate protocol cooperates with the circuit design. Except for thestandby current of microampere level, no power is needed when notrefreshing, which further reduces power consumption and realizes alonger standby. Of course, when the board content is a data streamencapsulated by a private protocol, the first control circuit 12 alsoneeds to convert the data stream to the data format that can be used forthe display of the first display screen 13 and the second display screen14.

For example, the private protocol is designed based on the Bluetoothtransmission protocol, which defines the data protocol when receivingdata and sending data. Specifically, the data format of the privateprotocol is shown in Table 1.

TABLE 1 Private protocol data format Field Name of Field Length AA + AAData header 2 Bytes 00 Designated AP, the corresponding designated 1Byte AP processing the sent data lengthH + Length of data 2 ByteslengthL 55 Byte indicating the data command 1 Byte AP AP indicating APfrom which the data is sent 1 Byte MAC To which the data is sent 6 Bytesdatacount Total number of packages 1 Byte datanum Number of the currentdata package 1 Byte data data 256 Bytes checksum check codes 3 Bytes0D + 0A End of data 2 Bytes

For example, the data format of sending display screen data (usually 256bytes) isAA+AA+00+lengthH+lengthL+55+AP+MAC(6)+datacount(1)+datanum(1)+data(256)+checksum(3)+0D+0A.

Specifically, the format of the command for the provide protocol isshown in Table 2.

TABLE 2 Format of the command for the provide protocol field Name offield length AA + AA Data header 2 Bytes 00 Designated AP 1 Byte MAC Towhich device the data is send 6 Bytes lengthH + Length of data 2 ByteslengthL A0 Byte indicating the data command 1 Byte command Command 1Byte command_next Status of the next command 1 Byte checksum Check codes3 Bytes 0D + 0A End of data 2 Bytes

For example, the format of sending a command(usually 20 bytes) is:AA+AA+00+lengthH+length1+A0+command(1)+checksum(3)+0D+0A.

It should be noted that the data format and command format of theabove-mentioned private protocol are merely illustrative, and it isconceivable that similar private protocols can also be applied to thepresent disclosure, and the protection scope should not be limited tothis example.

For example, the first communication circuit 11 may also be configuredto receive the board content from an electronic device through nearfield communication technology (NFC) and/or Bluetooth communicationtechnology. When the electronic device is a mobile terminal (mobilephone, etc.), it more convenient to use NFC or Bluetooth.

For example, as shown in FIG. 2 , the electronic board may furtherinclude a power management circuit 16 and a battery 17 for realizingpower supply and management of various components of the entireelectronic board.

The following briefly introduces the working process of the electronicboard.

When the first communication circuit 11 receives the handshake protocolmessage, the first control circuit 12 wakes up the first communicationcircuit 11 to receive the board content. The first control circuit 12controls the display driving circuit 15 to drive the first displayscreen 13 and the second display screen 14. The first display screen 13and the second display screen 14 update the screen after receiving thecomplete data. The power of the whole process is provided by the battery(rechargeable battery or replaceable battery) 17, and is managed by thepower management circuit 16.

The second aspect of the embodiments of the present disclosure providesan electronic device described above.

As shown in FIG. 3 , the electronic device includes a data receivingcircuit 21, a second control circuit 22, and a second communicationcircuit 23.

The data receiving circuit 21 is configured to receive the first boarddata to be displayed on the electronic board. The first board data isunique data of the electronic board. For example, the first board dataincludes: personnel related data corresponding to the scenario of thetable plate (Such as the name of the participant, work unit, title,etc.), the working station-related data corresponding to the scenario ofthe working station plate (such as the number of the working station,the name of the person at the working station, photos, etc.), ormeeting-related data (such as meeting arrangement information, etc.)corresponding to the scenario of the conference room door plate. Thedata receiving circuit 21 is also configured to receive a user'sselection of a background template.

The information displayed on the template may be input to the datareceiving circuit by the user through the user operation interface ofthe electronic device, or may be created by the user through other toolsand uploaded to the electronic device.

For example, the data receiving circuit 21 may be a data receivingcircuit electrically connected to an external input device, and isconfigured to convert the input signal from the external input deviceinto corresponding data information. When the electronic device is acomputer (PC, laptop, etc.), the external input device can be a mouse,keyboard, etc., and when the electronic device is a mobile device(mobile phone, PAD, etc.), the external input device can be a touchcontrol mechanism, keys or external keyboard, etc.

The second control circuit 22 is configured to generate a board contentbased on the first board data and the second board data. The secondboard data is background template data, and the board content is inimage format. The background template data may be locally pre-storedbackground template data.

For example, the second control circuit 22 is further configured togenerate content in a picture format with a preset resolution accordingto the first board data and the second board data. For example, theresolution is a preset picture resolution value that is small in filesize but can meet the display requirements of the electronic board. Inthis way, the board content is processed into a picture format file withthe preset resolution, which minimizes the burden of data transmissionbetween the electronic device and the electronic board, therebyimproving the efficiency of data transmission.

In some embodiments, the electronic boards include multiple groups, andeach group includes one or more electronic boards. The secondcommunication circuit 23 is configured to send the board content to oneor more electronic boards.

As an embodiment, when the board content is sent to one or moreelectronic boards, the electronic board directly displays the boardcontent.

Here, the one or more electronic boards as the sending destination maybe pre-set electronic boards, or electronic boards selected by the userby operating the electronic device. For example, there are multipleelectronic boards arranged in the meeting place. For each electronicboard, the board content to be displayed is usually different from otherelectronic boards. If the board content that needs to be displayed on acertain electronic board is generated, the instruction will be issued tosend the board content to the corresponding electronic board.

It can be seen from the above embodiments that the electronic deviceprovided by the embodiments of the present disclosure receives the boarddata and generates board content, and sends it to the designatedelectronic board for display, so that the electronic board itself onlyneeds to display the board content, thereby reducing the burden ofelectronic boards.

For example, the second communication circuit 23 may include at leastone of a wired communication circuit (such as USB) and a wirelesscommunication circuit (such as WIFI, Bluetooth, and Near FieldCommunication (NFC)). In some embodiments, the communication between thesecond communication circuit 23 and the electronic board can be achievedthrough wireless communication. For example, the second communicationcircuit 23 is configured to send the board content to a designatedelectronic board through wireless communication technology; wherein, theboard content is a data stream encapsulated by a private protocol. Forexample, the private protocol may include a Bluetooth private protocolor a 2.4 GHz private protocol. In this way, the board content is sentthrough wireless communication, and the electronic board does not needto be connected to the electronic device by wire, which makes the use ofthe electronic board more convenient. At the same time, the low-powerprivate protocol ensures the safety of transmission. In addition, theprivate protocol cooperates with the circuit design. Except for thestandby current of microampere level, no power is needed when notrefreshing, which further reduces power consumption and realizes alonger standby.

For example, the second communication circuit 23 is configured to sendthe board content to a designated electronic board through near fieldcommunication technology and/or Bluetooth communication technology. Whenthe electronic device is a mobile terminal, it can communicate with theelectronic board through NFC or Bluetooth communication, which is moreconvenient to use.

As an embodiment, when the electronic device is a computer (PC, laptop,etc.), it can communicate with the electronic board and/or otherelectronic devices (including mobile terminals) in a wired or wirelesscommunication manner. For example, when the electronic device is acomputer (PC, laptop, etc.) and communicates in a wireless manner, thesecond communication circuit 23 may be a wireless transmitting module,as shown in FIG. 4 , the wireless transmitting module may specificallyinclude: USB interface circuit 231, transmission controller 232,wireless transmission circuit 233, USB power management circuit 234. TheUSB interface circuit 231 and USB power management circuit 234 are bothconnected to the USB interface 24 of the electronic device through a USBconnection line. The transmission controller 232 is configured toconvert the board content sent by the electronic device into wirelesscommunication data, and transmitting the wireless signal through thewireless transmission circuit 233.

In some embodiments, the combination of a computer and a wirelesstransmitting module can be regarded as an electronic device. In thiscase, with respect to the data receiving circuit 21 and the secondcontrol circuit 22, the second communication circuit 23 may be acomponent physically separate from them. In other words, the secondcommunication circuit 23 may be a component attached to a computerincluding the data receiving circuit 21 and the second control circuit22 through a USB interface.

The electronic device is mainly used to edit the information of theparticipants of the meeting, make complex background templates, etc. Itsmain functions may include: verifying the produced board content in thepicture format to detect whether it meets the requirements; or, theboard content is further processed into the required picture quality andresolution to reduce the amount of data and improve transmissionefficiency; check the signal status of the electronic board, batterypower, or check the status of wireless transmission; specify theelectronic board that needs to be refreshed; built-in several backgroundtemplates for people to choose, and people can edit text (select font,adjust position, etc.) and pictures (photos, icons, etc.) based on thetemplate; people can send the board content to the designated electronicboard via wired or wireless means.

For example, one of the methods of using the electronic device is asfollows:

Place the electronic board at the designated position of the conferencetable;

After the relevant electronic board operating software is installed onthe electronic device, the wireless transmitting module is connected tothe wired interface (such as USB) of the computer;

The user inputs the to-be-displayed board data through the useroperation interface of the electronic device (such as the uppermachine), such as the related information of the participants in thescenario of the table plate, the conference room related information inthe scenario of the room number plate, and the working station plateusage information in the scenario of the working station plate, and thebackground template selection information. Then, the board content isgenerated based on board data. The board content can be generated by theelectronic device according to a pre-generated template and theinformation filled in the template by the user, and the board contentcan be information to be displayed in a picture format or non-pictureformat information generated by the electronic device;

After the electronic device verifies the board content, it sends theboard content to the electronic board.

In some embodiments, when the electronic device is a mobile terminal,the electronic device also has functions such as image processing andtemplate making, and can also have two types of wireless communication:private protocol transmission based on Bluetooth hardware transmissionand NFC transmission to ensure the convenience and safety of datacommunication. The main functions of the mobile terminal can include:receiving the board content sent by the electronic device in the form ofa computer and detecting whether it meets the requirements; or, furtherprocessing the board content to the required picture quality andresolution to reduce the amount of data and improve transmissionefficiency. The mobile terminal also can check the status of electronicboards and wireless transmission status; can specify the electronicboards that need to be refreshed, and set the transmission mode; canselect templates with built-in several background templates, and canedit texts (select font, adjust position, etc.) and pictures (photos,icons, etc.) on the basis of templates.

The method of using the electronic device in the form of a mobileterminal is briefly introduced as follows:

The dual-screen electronic ink screen is placed at the designatedposition of the conference table.

The mobile terminal is installed with the relevant electronic boardapplication, and the user inputs the board data to be displayed in themobile terminal, such as the relevant information of the participants inthe table plate scenario, the meeting room information in the roomnumber plate scenario, the usage information of the working stationplate in the working station plate scenario, and the background templateselection information; then, the board content is generated according tothe board data.

After the user verifies the board content through the mobile terminal,the board content is sent to the designated electronic board through alow-power private protocol, or the board content is transferred to thedesignated electronic board through NFC or Bluetooth.

In some embodiments of the present disclosure, a system for controllingan electronic board is proposed, which includes a display screen, andthe data receiving circuit 21, the second control circuit 22, and thesecond communication circuit 23 as described above. It should beunderstood that this system may include electronic device as describedabove. Alternatively, the system may include: a terminal deviceincluding the display screen and the data receiving circuit 21, and acloud server including the second control circuit 22 and the secondcommunication circuit 23. The terminal device communicates with thecloud server through a known wireless communication technology. In otherwords, the data receiving circuit 21, the second control circuit 22, andthe second communication circuit 23 as described above can bedistributed in different physical devices according to actual needs.

In the third aspect of the embodiments of the present disclosure, anelectronic board system is proposed.

The electronic board system includes: any embodiment of at least oneelectronic board or an arrangement or combination of the embodiments,and any embodiment of at least one electronic device or an arrangementor combination of the embodiments.

As shown in FIG. 5A, the electronic board system may include differentimplementations.

As an embodiment, as shown in FIG. 5B, the electronic board systemincludes an operating terminal (PC, laptop, etc.) and an electronicboard.

The user first determines the information and the number ofparticipants, designs the background and names and other informationthrough the operation terminal, and then the board content is output ina picture format. The picture format can be a format that the operationterminal can support. In this way, with the operating terminalgenerating the board content, the size of the board content in thepicture format can be reduced through algorithms, and the operationterminal may determine whether the board content in the picture formatis qualified. In addition, the user can also select the built-intemplate through the operating terminal for picture production andverification. After the board content in the picture format is prepared,it is connected to the wireless sending module through the USB port 24of the operating terminal to transmit the data stream encapsulatedaccording to the private protocol.

The USB power management circuit 234 obtains power from the USBinterface of the operating terminal, and the interface circuit 231 thatdrives the wireless transmission receives the data stream and iscontrolled by the transmission controller 232. The wireless transmissioncircuit 233 sends handshake protocol messages and the data streamaccording to the rules specified by the private protocol.

After the first communication circuit 11 of the electronic boardreceives the handshake protocol message, the first control circuit 12wakes up the first communication circuit 11 to receive the data stream,and the first communication circuit 11 controls the display drivingcircuit 15 to drive the first display screen 13 and the second displayscreen 14. The first display screen 13 and the second display screen 14update the screen after receiving the complete data stream to completethe display of the board content. The power of the whole process isprovided by the battery (rechargeable battery or replaceable battery) 17and managed by the power management circuit 16.

As another embodiment, as shown in FIG. 5C, the electronic board systemincludes an operating terminal (PC, laptop, etc.), a mobile terminal(mobile phone, etc.), and an electronic board.

The user first determines the information and the number of participantsof the meeting, designs the background and names and other informationthrough the operation terminal, and then the board content is output ina picture format. The picture format is a format that the operationterminal can support. Then, the operating terminal sends the boardcontent in the picture format to the mobile terminal through wirelesscommunication or USB wired connection.

After the mobile terminal receives the board content in the pictureformat, the board content is further processed. The picture size isreduced through the algorithm, the picture is determined whether it isqualified through verification, and the mobile terminal approaches theelectronic board to send, through Bluetooth or NFC, a handshake protocolmessage and data flow encapsulated by a private protocol.

After the first communication circuit 11 of the electronic boardreceives the handshake protocol message, the first control circuit 12wakes up the first communication circuit 11 to receive the data stream,and the first communication circuit 11 controls the display drivingcircuit 15 to drive the first display screen 13 and the second displayscreen 14. The first display screen 13 and the second display screen 14update the screen after receiving the complete data stream to completethe display of the board content. The power of the whole process isprovided by the battery (rechargeable battery or replaceable battery) 17and managed by the power management circuit 16.

It should be noted that the difference between the names of the mobileterminal and the operating terminal here is just for distinction. Infact, both the mobile terminal and the operating terminal are specificexamples of electronic devices.

In this embodiment, the addition of the mobile terminal only addsfurther processing and verification of the board content, which improvesthe data transmission efficiency and the accuracy of the displayedcontent of the electronic board.

As another embodiment, as shown in FIG. 5D, the electronic board systemincludes a mobile terminal (mobile phone, etc.) and an electronic board.

The user first determines the information and the number of participantsof the meeting, designs the background and names and other informationthrough the mobile terminal, and then the board content is output in apicture format. The picture format can be a format that the mobileterminal can support. Then the board content in the image format isprocessed to reduce the file size of the board content in the imageformat, and is checked whether it meets the requirements. Then themobile terminal approaches the electronic board to transmit, throughBluetooth or NFC, the handshake protocol message and data streamencapsulated by the private protocol.

After the first communication circuit 11 of the electronic boardreceives the handshake protocol message, the first control circuit 12wakes up the first communication circuit 11 to receive the data stream,and the first communication circuit 11 controls the display drivingcircuit 15 to drive the first display screen 13 and the second displayscreen 14. The first display screen 13 and the second display screen 14update the screen after receiving the complete data stream to completethe display of the board content. The power of the whole process isprovided by the battery (rechargeable battery or replaceable battery) 17and managed by the power management circuit 16.

It should be noted that, as can be seen from this embodiment, theelectronic device can be implemented by a mobile terminal, which is moreconvenient to use.

The fourth aspect of the embodiments of the present disclosure providesa control method executed by an electronic board, which can solve, to acertain extent, the problem of waste of resources of traditional boards.

The control method executed by the electronic board includes:

Step 31: receiving the board content to be displayed;

Step 32: displaying the received board content on the display screen ofthe electronic board. It should be noted that in the case where theelectronic board only includes the first display screen, in step 32,only the first display screen displays the board content.

It can be seen from the above embodiments that in the control method ofthe electronic board provided by the embodiments of the presentdisclosure, by receiving the board contents and displaying the boardcontents through the first and second display screens arranged oppositeto each other, it is convenient for the display of the boardinformation, eliminating the need to make paper boards, which is moreconvenient to use and saves resources. On the other hand, the boardcontents are displayed on both sides, besides other participants of themeeting, the participants corresponding to the board contents himselfcan also see the displayed content, which helps participants to findseats and correct false information.

For example, receiving the board content to be displayed, including:

The board content from an electronic device (alternatively, a controlsystem) is received through a wireless communication technology; whereinthe board content is a data stream encapsulated by a private protocol.

In this way, the board content is received through the wirelesscommunication mode without a wired connection with the electronicdevice, which makes the use of the electronic board more convenient. Atthe same time, the low-power private protocol ensures the safety oftransmission. In addition, the private protocol cooperates with thecircuit design. Except for the standby current of microampere level, nopower is needed when not refreshing, which further reduces powerconsumption and realizes a longer standby.

In the fifth aspect of the embodiments of the present disclosure, amethod for controlling electronic boards is provided, which can solve,to a certain extent, the problem of wasting resources of traditionalboards.

The method for controlling the electronic board is executed by a mobilephone or an upper machine and includes:

Step 41: receiving the first board data input by the user on the useroperation interface, where the first board data is unique data of theelectronic board;

Step 42: generating the to-be-displayed board content according to thefirst board data and the second board data, the second board data isbackground template data, and the board content is the content in apicture format;

Step 43: sending the board content to one or more electronic boards.

It can be seen from the above embodiments that the method forcontrolling electronic boards provided by the embodiments of the presentdisclosure receives board data and generates board content, and sends itto the electronic board for display, so that the electronic board itselfonly needs to display the board content, thereby reducing the burden ofelectronic boards.

For example, generating the to-be-displayed board content includes:generating content in a picture format with a preset resolutionaccording to the first board data and the second board data.

For example, the resolution is a preset picture resolution value that issmall in file size but can meet the display requirements of theelectronic board. In this way, the board content is processed into apicture format file with a preset resolution, which minimizes the burdenof data transmission between the electronic device and the electronicboard, thereby improving the efficiency of data transmission.

For example, sending the board content to one or more electronic boards,including:

The board content is sent to a designated electronic board throughwireless communication technology; wherein, the board content is a datastream encapsulated by a private protocol.

In this way, the board content is sent through wireless communication,and the electronic board does not need to be connected to the electronicdevice by wire, which makes the use of the electronic board moreconvenient. At the same time, the low-power private protocol ensures thesafety of transmission. In addition, the private protocol cooperateswith the circuit design. Except for the standby current of microamperelevel, no power is needed when not refreshing, which further reducespower consumption and realizes a longer standby.

In the present disclosure, the control circuit includes hardwarecomponents capable of implementing control functions such as aprocessor; the communication circuit includes hardware componentscapable of implementing communication functions such as an interfacecircuit; and the data receiving circuit includes hardware componentscapable of implementing data receiving functions such as a transceiver.
